We identified factors associated with delay in presentation and misdiagnosis of testicular torsion. Compared with acute cases, delayed presentations were more likely to report isolated abdominal pain, developmental disorders, and history of recent genital trauma. Failure to perform a genitourinary examination or scrotal imaging was associated with misdiagnosis.

Acute idiopathic scrotal edema (AISE) is regarded as a rare cause of scrotal pain, swelling and erythema. Testicular torsion, torsion of the appendage, epididymitis, hernia and hydrocele are the most common causes of acute scrotum. The clinical symptoms of AISE are usually mild and the characteristic Doppler sonography findings make it a valuable differential diagnosis, which can help to avoid unnecessary exploration.

Acute scrotum is a challenging emergency situation in children, adolescents and adults with a variety of underlying conditions and causes. In cases with a clinical suspicion of torsion of the spermatic cord, immediate surgical exploration is mandatory. This article details the surgical management of this condition. Any delay in restoring testicular blood supply may cause irreversible loss of vital testicular tissue.

OBJECTIVE: To investigate the role of cordycepin in testicular ischemia/reperfusion injury in rats. MATERIALS AND METHODS: Forty Wistar albino rats were randomly divided into four groups, as follows: group one, control (C); group two, torsion and ischemia (I); group three: detorsion with ischemia-reperfusion (IR); and group four, detorsion/cordycepin. The rats were then analyzed macromorphologically and histopathologically, and blood tests were performed. Specifically, the total oxidant status (TOS) and total antioxidant status (TAS) were determined, and malondialdehyde (MDA), tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β levels were analyzed...

PURPOSE: A rapid test for testicular torsion in children may obviate delay for testicular ultrasound. This study assessed testicular tissue percent saturation of oxygen (%StO2) measured by trans-scrotal near-infrared spectroscopy (NIRS) as a diagnostic test for pediatric testicular torsion. METHODS AND FINDINGS: This was a prospective comparison to a gold standard diagnostic test study that evaluated NIRS %StO2 readings to diagnose testicular torsion. Gold standard for torsion diagnosis was standard clinical care...

Vinpocetine is a potent antioxidant and free radical scavenger. We investigated the effects of vinpocetine on torsion/detorsion (T/D) induced testicular damage, HSP-70 expression and germ cell apoptosis in rats. Sixty Wistar albino adult male rats were divided into five groups of 12. The groups comprised a control group, a sham treated group, a T/D group, a vinpocetine treated group, and a T/D plus vinpocetine treated group. The left testis of each rat was subjected to unilateral torsion followed by detorsion after 2 h...

The technique of triggering the cremasteric reflex and its respective signaling pathway is not described uniformly throughout the literature. As this reflex is a useful sign in diagnosing testicular torsion, orchitis, varicocele, and undescended testis, it seems desirable to identify and define the correct mechanism. Our aim was to investigate how the cremasteric reflex and its signaling pathway are described in the current literature and how the variability of the innervation of the inguinal region could affect the frequency of this reflex...

INTRODUCTION: A growing number of patients are arriving at our tertiary care center for evaluation of possible testicular torsion using ambulance or helicopter transport. In many cases the parents arrive by car before the patient arrives. Are these advanced methods of medical transport worth the expense and risk in the case of suspected testicular torsion? OBJECTIVE: We evaluated the total number of patients presenting to our emergency room for suspected testicular torsion to see if the means of transport affected testicular survival...

REVIEW
Luis Guerra, Michael Leonard
Infants, children, and adolescents with inguinoscrotal pathology comprise a significant proportion of emergency department and outpatient visits. Visits to the emergency department primarily comprise individuals presenting with scrotal pain due to testicular torsion or torsion of the testicular appendages. At such time, immediate urological consultation is sought. Outpatient visits comprise those individuals with undescended testes, hydroceles, and varicoceles. Rare, but important problems, such as pediatric testicular tumours, may also present in the office setting...

BACKGROUND: Testicular torsion is a common problem and, to date, there is no agent to preserve testicular function following detorsion. Platelet-rich plasma (PRP), with its rich growth factor composition, has proven beneficial in regenerative therapy. It is believed that PRP has not been studied in testis for ischemia/reperfusion (I/R) injury. OBJECTIVE: This study investigated the effect of PRP in an I/R rat model 1 month after detorsion. STUDY DESIGN: Of 24 adult male Sprague-Dawley rats, 18 were randomly assigned into three groups, with six in each: control, I/R and I/R + PRP...

REVIEW
John E Kehoe, Matthew S Christman
PURPOSE OF REVIEW: Testicular remnants or nubbins are commonly found in the evaluation and treatment of cryptorchidism. While much debate focuses on the management of the nubbin itself, there is also great uncertainty and variation in the management of the contralateral descended testis. Herein, we review the relevant literature informing the decision to perform a contralateral orchiopexy. RECENT FINDINGS: Although there is very little recent literature directly addressing the question, some studies have better characterized differences in practice, the risk of intravaginal torsion in the contralateral testis and potential consequences in the selection of technique...

Testicular torsion is predominantly a disease of adolescence, but age itself should not be an exclusion criterion for the diagnosis. A lack of suspicion for testicular torsion in older patients may result in a missed or delayed diagnosis which jeopardizes the chance of testicular salvage. In this article, we report a case of testicular torsion in a 55-year-old Chinese man.

INTRODUCTION: Nitric oxide (NO) plays an important role in the ischemia and reperfusion process. In this study, we aimed to examine the effect of L-arginine, tadalafil, and their combination for prevention of the ischemia reperfusion injury after testis torsion in rats. METHODS: A total of 40 adult, male Sprague-Dawley rats were allocated into five groups. Three hours of left testicular torsion was performed in each group, excluding the control group. While the ischemia reperfusion (I/R) group had no treatment, I/R + Arg group received L-arginine, I/R + Td group received tadalafil and I/R + Arg + Td group received tadalafil and L-arginine 30 minutes before the detorsion...

Perinatal testicular torsion, defined as torsion occurring in the prenatal period or in the first month after birth, accounts for 10% of all cases of testicular torsion in pediatric patients. Most are extravaginal, and intravaginal torsion is rare. Its management is controversial, due to the low viability of the testis and the possibility of bilateral torsion. Ultrasonography is the method of choice to study testicular torsion. Combining B-mode and power Doppler imaging facilitates a fast reliable diagnosis...
